Brakes-GMC truck 1962

I have a 1962 GMC Truck I am restoring. Sorry it's not going to be original. Can I put a power brake system from a 1993 GMC truck with disc front brakes. I have the master cylinder and entire pedal assembly. In my 1962 GMC truck with front drum brakes ? Or How can I convert the front into disc brakes , without spending a $1000. Thanks for the help rodrock26
